This function is also known as the modulus on the absolute value function, for example:
In the given in the above graph, that is
In function 2:
In this function, It is an algebraic function that is
It is also a part of the quadratic polynomial function, and its value is
In function 3:

In the graph its value is:
Answer:
(c).
Step-by-step explanation:
h(t) = - 16 t² + 80 t
Coordinates of the vertex are:
<em>t</em> = - =
= <em>2.5 sec. </em>
<em>h</em> = - 16(2.5)² + 80(2.5) = - 100 + 200 = <em>100 ft</em>.
